WESTCHESTER COUNTY, N.Y. -- The Westchester County Department of Health has learned that a mosquito batch has tested positive for West Nile Virus in Westchester for the first time this year.

The mosquito batch had been collected by County Health Department staff in New Rochelle and sent to New York State Department of Health for testing.

Last year, seven positive mosquito batches were found in Westchester County and two human cases of West Nile Virus were reported. So far this year, there have been no reported human cases.

“This is the time of year when we typically start to identify mosquitoes that carry West Nile Virus in Westchester,” Sherlita Amler, MD said in a statement. “While it should not be a major cause for concern, it would be prudent for residents to use repellents when outdoors from dusk to dawn to avoid mosquito bites altogether.”

The Health Department will continue to trap and test mosquitoes and survey catch basins for mosquito larvae or standing water.
